Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for intensively controlling a large number of looms, and in particular, information on yarn defects in a yarn making process specific to each warp beam and each weft cone is previously stored. The present invention relates to a method of storing information on the central control unit side, transferring defect information of a yarn to a control device of a corresponding loom when necessary, and setting an optimum operating condition of the loom based on this information.

[Conventional technology]

For example, the invention of Japanese Patent Laid-Open No. 59-212658 discloses a method for controlling a loom group in which a central host CPU issues a command for stopping or starting the loom to a microcomputer of each loom. However, the group control method only gives information on prohibition or start-up of the loom and is not involved in the control of the weaving conditions during operation.

When actually operating the loom, for example, in an air jet loom, the number of rotations of the driving motor of the loom, the number of weft threads, the setting of the warp thread tension, the timing of opening and closing the weft insertion nozzle, the weft insertion A lot of control data such as setting of the pressure of the working air is required.

These control data can be set at a location distant from each loom by inputting to the control device of each loom through the terminal of each loom using the central control device.

On the other hand, in the process of making warp and weft threads, various thread information,
For example, the length of the yarn, the maximum winding diameter, and the defect information of the yarn in the yarn making process are recorded, but the defect information of the yarn in the yarn making process is not used in the process of the weaving machine. If the beam for supplying the yarn and the cone for supplying the weft yarn are of the same type, the operating conditions set based on the type of yarn were constant throughout the yarn consumption process.

[Object of the Invention]

Therefore, an object of the present invention is to realize optimum control of a loom by effectively utilizing the yarn defect information relating to the yarn beam and the weft yarn cone in the weaving process to be set on the loom during the weaving process.

[Outline of Invention]

Therefore, in order to effectively utilize the yarn defect information in the yarn making process in the weaving process, the present invention stores the yarn defect information in the yarn making process in the memory of the central control unit, and warps the yarn beam or the weft yarn cone. Of the warp beam or weft thread cone set on the loom is read and transferred to the control device of the corresponding loom, and the loom control device detects the yarn defect information during weaving based on the yarn defect information. The operating condition of the loom is temporarily changed when the defective portion is consumed. Therefore, the loom can always be operated under optimum operating conditions.

[Configuration of centralized control device]

First, FIG. 1 shows a configuration of a centralized control device 1 which is a premise of the centralized control method of the present invention. The centralized control device 1 includes a central control device 2 as a main part. A CPU 5 inside the central control unit 2 is connected to an input device 7 such as a keyboard, an output device 8 such as a printer, an external memory 9 and an interface 10 via an input / output port 6 or directly. On the other hand, terminals 4 ₁ , 4 ₂ ,
· 4 _n are respectively connected to the control unit 3 _1, 3 ₂ ·· 3 _n of the weaving machine, also via an interface 11 _1, 11 ₂ ·· 11 _n and the data bus 12, Li by the above interfaces 10 It is connected to CPU5.

The central control unit 2 takes in control data necessary for the control units 3 ₁ , 3 ₂ ... 3 _n of each loom by a control program based on the control, calculation and storage functions of the CPU 5, and stores it in the memory 9. Let's leave the control device for each loom 3 ₁ , 3 ₂ ... 3 _n
The required control data is transferred through the data bus 12 based on the request from the.

Such control data is input through an input device 7 such as a keyboard, is created while being confirmed by an output device 8 such as a display, and after creation, is stored in a memory 9 together with a product type number unique to a fabric product. . In this way, in other words, for each product type number, the number of rotations of the loom per unit time, the number of weft threads per unit length, the warp thread tension during weaving, and the weft insertion nozzle on / off. Timing, air pressure setting for weft insertion,
Other necessary weaving condition data is created in advance and stored in the memory 9. Therefore, the subsequent designation of the control data is easily performed by specifying only the product type number.

The contents of the control data set in this way are changed as necessary, and are changed each time actual weaving or trial weaving is performed in order to realize optimum conditions.

FIG. 2 shows a procedure for changing the internal control data for each product type number. When the operator selects "change of product type" through the input device 7, the program required for changing the product type is automatically started. When the type number to be changed is designated here, the CPU 5 reads the control data of the designated type number from the memory 9 and displays it on the output device 8 or the like. Therefore, the operator selects an item to be changed from the control data and changes the numerical value to a required value. After such a change, the CPU 5 newly stores the changed control data in the memory 9 as the data of the product type number. In this way, the product type is changed.

On the other hand, the yarn information is stored inside the memory 9 together with the beam number of the warp beam and the lot number of the weft cone. The beam number and the lot number are pre-filled in the beam and the cone in the preparation stage of weaving. The yarn information of the warp yarn is the total length of the yarn, the outer diameter of the beam, or the fluff in the previous step, such as the gluing step,
This is data of defect information such as uneven glue and thread breakage. In addition, the yarn information of the weft yarn is data such as the length of the yarn and the thickness of the yarn in addition to defect information such as yarn breakage in the manufacturing process, that is, in the lot.

In this way, the central control unit 2 stores in the memory 9 outside the CPU 5 a series of work-in-progress data, that is, control data for each loom number, for each of the control units 3 ₁ , 3 _2, ... 3 _{n of} each loom. That is, the product type number, the warp beam number, and the weft lot number are sequentially stored as a queue.

〔Example〕

Next, FIG. 3 shows the sequence according to the centralized control method of the present invention.

This centralized control is executed by a centralized control program inside the CPU 5. First, CPU 5, upon receiving the command to start the centralized control to start the control, specify "1" loom number example, receives necessary data from the terminal device 4 _first controller 3 ₁ of the loom To do. The terminal unit 4 _1, addition to providing the data necessary for the control of the corresponding loom control device 3 ₁ of the loom, incorporating needs signal from the corresponding loom weaving, it temporarily stores the it, the central When a data transfer command is received from the control device 2, it is transferred to the CPU 5.

Here, CPU 5 from the received data, the control unit 3 ₁ of the loom, it is determined whether a request for data. By the time the control unit 3 ₁ is requesting data, CPU 5
Reads in-process data from the external memory 9,
By specifying the product type number, the warp beam number, and the weft lot number, the control data and yarn information corresponding to the numbers are read out, and the interface 10,
The data is transferred to the corresponding terminal device 4 ₁ through the data bus 12 and the interface 11 ₁ . Here, the terminal device 4 ₁ stores the control data and the thread information of the transferred becoming the model number, held as necessary for the operation of the control device _3-one correspondence of the loom data, necessary control based on it I do. In addition,
The yarn information, especially the yarn defect data, is used for temporarily setting the rotation speed of the loom to be low near the defective yarn.

On the other hand, the CPU 5 reads the next loom number, for example, "2", and performs the same processing for it.

In such a process, when there is no request for control data from the control devices 3 ₁ , 3 _2, ..., 3 _n , the CPU 5 branches from the data transfer routine and enters the registration routine to determine whether or not there is a product type registration request. The presence / absence of a beam registration request and the presence / absence of a lot number registration request are sequentially determined.

When a product number registration request is issued and the product is ready for registration, the operator first inputs the product number, then the control data corresponding to that product number, and then issues a data registration command. . By such operation,
The central controller 2 registers control data for each product type number.

When a beam registration request or lot registration request is issued and it becomes possible to register, the operator enters the loom number, then the product type number, and then the corresponding beam number and its thread information and The corresponding cone number and the thread information of the weft thread are input and registered in the external memory 9 as work-in-progress data.

In this manner, the loom number, the product type number, the beam number, and the lot number corresponding to the loom number are preliminarily input and registered as work-in-progress data for all the loom in the central controller 2.

Next, FIG. 4 shows another embodiment of the centralized control method of the present invention.

First, the CPU 5 controls the loom control device after the start of centralized control.
It is judged whether or not there is a control data transfer request from 3 ₁ , 3 ₂ ... 3 _n . For example, when the control unit 3 ₁ of the loom there is transfer request, CPU 5 starts a routine of the data transfer, first, performs a determination of whether the control data data requested for transfer is for varieties, so If not, proceed to the next step and transfer the required thread information, but when the control data is requested due to the type change, the type number of the next work-in-process type is searched and after transferring after reading the necessary control data, and transfers the thread information by lot number of beam number and weft warp to the control unit 3 ₁ of the loom. By repeating such an operation for other control devices in sequence for 3 ₂ ... 3 _n , the central control device 2 causes the control devices 3 ₁ , 3 ₂ ...
・ Concentrate control of 3 _n .

When there is no data transfer request at the time of determining the control data transfer request, the CPU 5 enters a registration routine and determines whether or not the operator has registered the product type, the yarn information, and the transfer order. When the operator inputs a command for product type registration to the CPU 5 when newly inputting control data corresponding to the product type number, the product type registration step is started. Therefore, after registering the product type number, the operator sequentially inputs the control data corresponding to the product type number. In this way, registration for all product types is performed. At the end of such product type registration, the control program returns to the first step again.

Further, when the operator requests registration of thread information, the CPU 5 starts the program. Therefore, after registering the beam number and the lot number, the operator sequentially inputs the yarn information of the weft yarn and the warp yarn. When all the input is completed, the control program
Return to the first step again.

Further, when the operator requests registration of the transfer order, the centralized control device 1 starts the step. Therefore, after specifying the loom number, the operator inputs the product type number while designating the transfer order based on the weaving order of the loom, and further sequentially inputs the corresponding beam number and lot number. Thus, for example the control device 3 ₁ of the loom, varieties to be woven numbers, etc. warp beam numbers and weft cone lot number at that time is input with a transfer order when they are identified.
Accordingly, in this control program, even when such warp beam or weft of the cone is not definite whether it is supplied to the advance which the loom, since previously the thread information registration can be performed,
This is advantageous in the efficiency of the input work as compared with the embodiment of FIG. 3 in which the thread information registration cannot be performed until they are specified.

〔The invention's effect〕

 In the present invention, the following unique effects are obtained.

When a new warp beam or weft cone is set on a loom, defective information about the warp beam or weft cone that has been set during the yarn making process is transferred to the controller of the corresponding loom. Based on the defect information of, when the defective part of the yarn is consumed during weaving,
By temporarily changing the operating conditions of the loom, for example, the rotational speed of the loom is temporarily set low, so that the loom operating in a state corresponding to the type of yarn will weave the defective portion of the yarn near the loom. Since the operating condition is changed to a condition more suitable for the defective portion, the loom can always be operated under the optimum operating condition.
